7 string bridge.. HELP

A while back one of my pivot points on my Ibanez RG 7620. It is a licensed Floyd Rose 7 string bridge, and I am not sure if they make them anymore. I was tweaking it, adjusting the height, when it broke. The upper part where you adjust, so it is working, but i can't adjust it anymore,.

Anyways, I was wondering if I could be able to replace the pivot point, or if a have to buy a whole new bridge alltogether? Any good recommendations for substitute bridges?
